UARTE Interrupt is not working at all

[jswcomkr]

Hi.

I'm developing application that is needed to include  UARTE Interrupt.

I can drive UART interrupt well(not UARTE), but UARTE is not working.

#include <stdbool.h>
#include <stdint.h>
#include <string.h>
#include "nrf_delay.h"
#include "nrf_gpio.h"
#include "nrf_uarte.h"
#include "SEGGER_RTT.h"


void UARTE0_UART0_IRQHandler(){
	SEGGER_RTT_printf(0, "test\n");
    if(NRF_UARTE0->EVENTS_ENDRX){
		SEGGER_RTT_printf(0, "test\n");
    }

}

int main(void)
{

	static uint8_t txBuffer[7] = "TEST\r\n";
	static uint8_t rxBuffer[20] = {0};

    NRF_UARTE0->BAUDRATE = NRF_UARTE_BAUDRATE_9600;
    NRF_UARTE0->PSEL.TXD = 19;
    NRF_UARTE0->PSEL.RXD = 18;
    NRF_UARTE0->CONFIG = NRF_UARTE_HWFC_DISABLED;
    NRF_UARTE0->ENABLE = (UARTE_ENABLE_ENABLE_Enabled << UARTE_ENABLE_ENABLE_Pos);

    NRF_UARTE0->TXD.PTR = (uint32_t)((uint8_t *) txBuffer);
    NRF_UARTE0->TXD.MAXCNT = sizeof(txBuffer);
    NRF_UARTE0->TASKS_STARTTX = 0;

    NRF_UARTE0->RXD.PTR = (uint32_t)((uint8_t *) rxBuffer);
    NRF_UARTE0->RXD.MAXCNT = sizeof(rxBuffer);
    NRF_UARTE0->TASKS_STARTRX = 1;


    //NRF_UARTE0->INTENCLR = 0xFFFFFFFF;
    NRF_UARTE0->INTENSET = (1 << 2);

    NVIC_ClearPendingIRQ(UARTE0_UART0_IRQn);
    NVIC_SetPriority(UARTE0_UART0_IRQn, 5);
    NVIC_EnableIRQ(UARTE0_UART0_IRQn);


    SEGGER_RTT_printf(0, "teTN\n");
    while (true)
    {
    	NRF_UARTE0->TASKS_STARTTX;
    }
}

Here is my code. Would guide me please?

Thank you.

I cannot think of any good explanations as to why it works with UART, but not with the UARTE. Can you try to debug the app and check the peripheral event registers to see which events are set? Maybe EVENTS_ERROR is set instead.
